The Hex Frog Juicer automatically and instantly switches the polarity of the frog as the engine passes over the turnout. No more complicated wiring or electro-mechanical switches are needed. Instead you simply connect power to the Frog Juicer and a single wire to the frog. The Frog Juicer takes care of the rest!

Each Hex Frog Juicer can control the polarity of DCC power for up to six frogs on all types of switches including turnouts, wyes, 3-ways, slips, crossings and crossovers. Using a Hex Frog Juicer is especially helpful for double crossovers and crossings as it dramatically simplifies the wiring for these types of switches.

The Hex Frog Juicer can be used to switch the frogs for up to three reverse loops or wyes. (You need to use two frog control outputs for each reverse loop and wye.)

Eliminates the need for mechanical switches to switch the frog polarity when the turnout is switched

Instant switching means no interruption to the engine or loss of sound

If you have ever struggled with wiring up the frogs on a switch, then you will want to seriously consider using the Hex Frog Juicer. It is simple to use, and just plain works.

How The Hex Frog Juicer Works

The Frog Juicer consists of six microprocessor controlled SPDT electronic switches. Each switch can sense and control the polarity of one frog. When the circuit detects a short greater than about 1.7 amps (plus/minus 10% with 2 amps the upper limit), it instantly switches the polarity of the frog. Two amps is below the reverse polarity detection point for most DCC circuit breakers and booster units so that the Frog Juicer will react before a fault is detected. In addition, the Frog Juicer switches so quickly that the brief current pulse will go unnoticed by the DCC system. Two amps is also enough current to power a single locomotive, and since only one locomotive can be on a frog at a time it is all the power that you need. The frogs need to be electrically isolated and have no other connections to the track or DCC system.

I purchased 2 of these, received one in non working condition, the company sent me a replacement ASAP. Not only a great product, but GREAT customer support. Hooked up the other one and it works like a dream. I ordered 2 more to complete my layout. What an easy way to get a turnout to work like it should.

You need the HFJ. You want the HFJ.

Everyone stop everything now! Go out and buy as many Hex Frog Juicers as you can! I've been into model railroading for about 50 years, and second only to the NCE radio system I use, the HFJ is the best product I've ever seen. It is pure genius, works like magic, is simple enough for even this old-timer-with-a-sore-back to install. And, it's Christmas all year long now. (You'll know what I mean when you install one!) As soon as the second half of my layout gets built, I'll be ordering 2 more. Did I mention they are GREAT!Nice job Fast Tracks!

My Review

Great little device. Two wires to your track bus and hook up six frogs to one HFJ. It really is that easy.

I have installed two of these so far, with a third one to go. The second HFJ was wired to a hand laid double cross over. The Tam Valley Web site has a simple schematic which shows you how to wire the frogs properly. Follow those instructions and you'll be off to the races in minutes. Got it right the first time without a hitch.

If I have one caveat it would be the price. At 70.00 bucks it is a bit steep and for people the price might be hard to justify.

Otherwise a great little product that has made wiring my layout this time around, incredibly easy and painless.
